Introduction to LabVIEWand Data Acquisition (DAQ)
systems
LabVIEW programs are called virtual instruments, or VIs, because their
appearance and operation imitate physical instruments, such as
oscilloscopes and multimeters. LabVIEW contains a comprehensive set of
tools for acquiring, analyzing, displaying, and storing data, as well as tools to
help you troubleshoot code you write.

In LabVIEW, youbuild a user interface, or front panel, with controls and
indicators. Controls are knobs, push buttons, dials, and other input
mechanisms. Indicators are graphs, LEDs, and other output displays. After
you build the front panel, you add code using VIs and structures to control
the front panel objects. The block diagram contains this code.
You can use LabVIEW to communicate with hardware such as data
acquisition, vision, and motion control devices, as well as GPIB, PXI, VXI,
RS232, and RS485 instruments.

Data Acquisition System(DAQ)
NIUSB- 6009
The data acquisition card receives different types of
signals from the sensors connected to the setup, the
signals are fed to the computer through different channels
available in the data acquisition card.
